Answer:

1. 7x+5y=19    

(+)-7x-2y=-16       step one

____________

\frac{3y}{3\\}=\frac{3}{3}                   step two

y=1

____________

since you have the value of y u can plug it in in either of the equations.

7x+5(1)=19        step three

____________

7x+5-5=19-5     step four

____________

\frac{7x}{7}=\frac{14}{7}

x=2                     step five

____________

You can check whether the answers are correct by plugging them back in.

7(2)+5(1)=19

14+5=19

19 equals 19 so it checks.

You can do the same thing for the rest.

Draw Line HI perpendicular to Line JK<br> (be sure to include appropriate markings)
kirill [66]

To draw line HI perpendicular to JK we need to follow the given steps:

Place your compass on the given point (point H). Draw an arc across the line on each side of the given point. Do not adjust the compass width when drawing the second arc.

From each arc on the line, draw another arc on the opposite side of the line from the given point (H). The two new arcs will intersect.

Use your ruler to join the given point (H) to the point where the arcs intersect (I).

HI is perpendicular to JK.

What is perpendicular?

Two distinct lines intersecting each other at 90°, or a right angle, are called perpendicular lines.

Properties of Perpendicular Lines

  • These lines always intersect at right angles.
  • If two lines are perpendicular to the same line, they are parallel to each other and will never intersect.
  • Adjacent sides of a square and a rectangle are always perpendicular to each other.
  • The sides of the right-angled triangle enclosing the right angle are perpendicular to each other.
